Description

一种液体口罩贴及防霾抗菌口罩 技术领域
本发明属于预防医学辅助耗材技术领域,具体涉及一种液体口罩贴,并进一步公开其制备方法,以及含有该液体口罩贴的防霾抗菌口罩。
背景技术
随着我国经济持续高速发展,城市化和工业化进程日益加快,工业生产、日常发电、汽车尾气排放等过程向空气中排放了大量残留物使空气中的颗粒物浓度大大增加,特别是PM10(空气中直径小于10um的极细颗粒物)和PM2.5(空气中直径小于2.5um的极细颗粒物),它们对空气质量和能见度等都产生了重要的影响。目前,影响我国城市空气质量的主要污染物是大气中漂浮的PM2.5颗粒,严重威胁着人们的健康。除此之外,空气中还漂浮着大量的致病细菌、病毒及多种有害气体等,都严重威胁着人类的健康。
挥发性有机物(VOCs),通常是指特定环境条件下容易蒸发或挥发的有机化合物,VOCs容易生成PM2.5和臭氧,导致光化学烟雾并加重灰霾,严重污染环境和影响人类健康。酸性气体,指能与碱作用生成盐的气体,污染空气中的酸性气体有二氧化碳、氯气、硫化氢、二氧化氮、氯化氢、二氧化硫等。酸性气体作为造成环境污染和导致生态破坏的主要气体是温室效应和酸雨泛滥的元凶。此外,如吸烟,厨房油烟等污染性气体也对健康构成较大的威胁。
再者,空气中漂浮的细菌、病毒等微生物也是呼吸道感染的重要来源,空气及空气中的飞沫、飞沫粒及尘埃是呼吸道感染的重要传播途径。经空气中传播的呼吸道疾病很多,如流行性感冒、麻疹、水痘、风疹、流行性 脑脊髓膜炎、非典型肺炎等。因此,预防呼吸道传染病主要是切断它的传播途径,改变空气及环境质量,控制或杀灭空气中的细菌、病毒及致病微生物。
研究表明,污染气体会对经呼吸***(肺部)、皮肤表皮、呼吸道***、神经***、免疫能力、肝脏、内分泌***等产生毒害作用,使人出现易疲劳、紧张等不良反应,并且降低工作、严重影响学习效率。长期处于空气质量较差的环境,不仅会引起呼吸功能下降、呼吸道症状加重,还会导致慢性支气管炎、支气管哮喘、肺气肿等疾病,严重的还会导致肺癌、鼻咽癌患病率的增加
为了防止细颗粒物、有害气体、细菌及病毒对人体的侵害,口罩成了人们生活中的必备品,目前的口罩主要应用的材料为传统的非织造布,这种材料的直径约十几微米甚至几十微米,孔径较大只能过滤较大的颗粒,对细颗粒物、有害气体、细菌病毒的拦截效果较差,无法满足人们的需求。
随着空气污染物的日益严重,各种专业的防雾霾、抑菌的功能性口罩应运而生。现有技术中防颗粒物及抑菌口罩主要是通过在口罩内层中增设过滤芯层和/或抑菌层实现的,所述过滤芯层多含有活性炭等吸附物用于吸附污染颗粒物之用,所述抑菌层多通过浸渍抑菌液的形式制得。上述功能性口罩能够有效去除多种污染颗粒物并具有一定的抑菌抑病毒作用。但是,诸如此类的功能性口罩中滤芯设置于口罩内层,一方面有吸附颗粒泄露导致误吸入的问题,另一方面也存在着不易清洗及解吸附困难的缺陷。另有一些功能性口罩是采用具有抑菌性能的材料编织制得,虽然解决了抑菌等问题,但依然存在多次清洗后抑菌及污染物吸附能力下降的问题。因此,现有技术中几乎所有的功能性口罩都无法实现长期使用的问题,即便是价格高昂的功能性口罩,使用次数也是有限制的,造成了较大的资源浪费,也给消费者造成较大的经济负担。
口罩贴是在现有功能性口罩基础上发展而来,其应用原理即是将原本置于口罩内层的滤芯层和/或抑菌层设置于口罩的外侧,在起到防雾霾及抑 菌效果的同时,可以通过更换相应的滤芯层和/或抑菌层实现口罩的多次反复使用,有效降低了消费成本。但是,现有口罩贴多是通过缝制或是黏贴于口罩的外侧,存在着缝制操作复杂或者黏贴不紧密的缺陷,限制了口罩贴使用的便捷性和有效性。
发明内容
